Similar letters of reference indicate corresponding giurie. y
My invention relates to that class of engines in which the power in deriverl from alternately heating and cooling atmospheric air, orfoilier'snitabie gaseous iuid, said oir or duid being Worked under compression, und the heut primarily communica-ted to it vby oil or other liquid, gos, or vapor, heated by o suitable iurnnee; and
The oreutiou, which idenomioate u. thermostatio engine, embraces various novelties iu the. method of working and in tiro construction of tine engine, which contribute materially to its success, the same including; en advantageous inode of importing heat to the nir in the working-cylinder 0i' the engine by the coursing; o'i iihot liquid through. n tubular structure inthe lower end of said cylinder, serving to lient n liquid surrounding the tub-es of said structure, into u'liiohrproliongetions of the pistou are malle to dip.
Alec, lhe-iorentioninoiudes o sprinkler or cooler to Athe exhaust oir in the upper portion of the working cylinder uitcr the semelles imported ocertuinzimounl'i oi" its' heat to n metallic reservoir or tran:afer-ehemher that serres to heat theiucoming air.
Besides tli'ese,'the invention includes rarious denils. as hcreinoter described, for making more peo' feet such system or 'method of working :s'hlghpresr nre hot-oir engine, iu which it'. is not intended to claim, lu'outlly, muslim-ing the heal:y from 'the furnace oyV het liquid, nor yet to rest-riet the .heating-liquida) nu,
nutiooler description, nud-the some moyeither .lne
mereurafnsiblo motel, steain, or oil, which latter il; will suiiee here to refer to es the heating-medium. Prior to describing the encino represented in the accompanying drawing,whici1 is' but one form of applying the invention, il; may here be remarked that., while but two working cylinders are here shown, with their pistons arranged to more simultaneously in roverse directions, and each, as usual in Asuch engines, only exerting power on the crank during its one or upstroke, itis preferred to use four cylinders, with their pistons and. cranks arranged to uvoid the cocu once oi' a deadwzenter, and operating to produce o, more regular motion. When four o 'fliuderslarenoe then the nir-"eceiver, hereinafter referred to, may v dispensed with, :ind-said cylinders made alterner y and successively to take the, place oi'. seid reccivea-z A iu the drawing represents en nir-receiver a cooler, in which the nir is eouuireseii till it renc the requisite pressure;
B B are the working cylinders; and G C'C, the pipes which convey the oir from the receiver to said-'cylinders through' ,'nlves D, when the sumo are opened for the purpose, and which is, during the ung-'stroke ,of the piston, or during o oor-- tion thereof, oenording to the periodof cutting on to work the air expansirely iu the cylinders. v
E E are the return-pipes, for the exhaust air and cooling-liquid, tothe receiveiiofg, Y A The air, after inline performed its duty in' ex oaxided and highly-heated state in either cylinder, he
' low thc istou F thereof is assed out from seid ovl P s c vinder, by end during the descent ot' the. piston, up through o metallic reservoir' or transfer-chamber, G, formed of suitably-seperated lomin or plates, to which it transmits 'o largo portion of its heet, for the purpose of heating the incoming' oir, to supply 'the next stroke or" the engine, and for preprozitorily cooling the exhaustnir oeiore itis passed into the working cylinder above the' pistou, where `it is further cooled, as will he liereiuiiiteridescribed.
Suid exhaust air is thus 'returned to 'the' working cylinder through valves H l, open during the descentot'thc piston, but closed in its ascenta The object oi tho epfvulro I is to dimiuishtho friction oi the slidevalve H,end protect it fwmpressure of the oir in the upper portion of the cylinder.
Thefariungoinent of the regeuerator or transfer-chamber@ between tile of the pluies oomprffsing it Loing weer` i edil-istmo Y The @melody-cooled osha-u the irsuscr-clwnber G, sind return to the. working cylinder above the piston, is there further cooled by o, spl ihlglcr, J, and, subsequeuily, thai is, in the next osceni ci' the pistou, expelled, by the letter, back `through valves K l zuid the rcturn-pioe E, to the receiver f3. The sprinkler J, in tifo upper poro of cach working cylinder, is supplied with cooling water,

To this end, the cooling-liquid is fed to the sprinkle hy o pipe, c, from jacket", U, arranged to snrronnd the 'ziirchemiserA but in open communication with the latter by o lower opening, d, so that the air ond weer or cooliogdiqnid returned by the pieton in its upeslrolgc through .the plee E, will readily Shen` respective places, and the cooling-liquid in @he jacko; U serre to keep the eir-reeeiver iight. The confined oir and in the receiver and cooler A, ocing o nou ille surieoe oi' the cooling-liquid rising through the opening ci, espeis said liquid into the showermon J, whenever the pressure 'in the noi-.zing cylinder is sui'- ilcienily below that; o the oir io tho receiver, rift-sr said coolingdiqoid has performed its duty within the cylinder, is returned, along with ibo cooled exizou nir, 'by the pieton, lo its lip-stroke, bock through the valves li pipe E, to ihe receiver A and its 'eolici U. These valves K. ii, which enerve? lha tn'coid purpose of'ienn'ningche cirund olio coolingiquid, are o o nrrong'eo as thai, when closed, they `.vill

vThe transfer-chamber G, :is hereinheihre referred to, made to impari heal, derived from the exhaust nir passing up through it, to the incoming air, which has to pass dorm through between the booting-plates of said chamber before io enters the cylinder below the piston. Here said incominguir is still further heated and high l y expanded, to give to it an effective propelling power ou the pistou, by hot oil or liquid iu the took L, which derives its lient-limo o larger mass oi hot liquid, circulated in d coil of pipe, il, oi' o, suitable furnace or generator, nud driven rapidly by any proper forcing device, 0, up through one set oi i-uhes, M, and down through another set of tubes, lli', contained .within a tenir, il, situated in the ing cylinder, ibo circulation ninos P and {,l. nud the hczfo from the hot liquid, time coursing the tubulin' otll'uciure iu the bottom ot the vorking oyliiuler,.being communicated to the liquid contained within he solsL, ioiihe purposefoheat ing the air in the n'oiliinf' cylinder.

Said piston F is likewise mode to retain the heat communicated to the air, and, at the same time, to protect the working cylinder from hoh air ,below the piston, by moons of a shield or prolongation, T, of n cylindrical form, and made to t the interior of the working cylinder, By thus constructing und providing the piston l?, the air and heating-liquid me kept intheir proper places, :md the cylinders kept cool 4while lche oir is heated bythe oiled surface ol the lsmin during its expansion within the cylinder.
